Close-up observations of the near-Earth asteroid Bennu have revealed many surprises, NASA announced today during the 50th Lunar and Planetary Conference in Houston. These include particle plumes and a much more rugged surface than had been anticipated.

Flying in space, remembered astronaut John Blaha—who made the first of his five missions, 30 years ago, this month—vanished in the flicker of an eye. On 13 March 1989, Blaha and his four crewmates launched aboard shuttle Discovery on the relatively “vanilla” STS-29 flight to deliver a major NASA communications satellite into space. Seated in the pilot’s seat, alongside future Johnson Space Center (JSC) Director Mike Coats, Blaha was joined by Mission Specialists Bob Springer, Jim Buchli and Jim Bagian. Most of the crew had been recycled from a pre-Challenger assignment to a flight which might have seen the first citizens of Indonesia and the UK to travel into space.

Dedicated to the memory of a former electrical installations lead for the Delta IV Program—30-year aerospace industry veteran Kurt Huschle—the second-to-last “single-stick” United Launch Alliance (ULA) Delta IV booster roared smoothly to orbit this evening (Friday, 15 March), laden with a critical military communications asset to support U.S. and allied warfighters across the globe.

Two U.S. astronauts rode into orbit, shoulder-to-shoulder with a Russian commander earlier today, when Soyuz MS-12 speared smoothly aloft from Site 1/5—the historic “Gagarin’s Start”—at Baikonur Cosmodrome in Kazakhstan. NASA flyers Nick Hague and Christina Koch were joined by seasoned cosmonaut Alexei Ovchinin for the on-time liftoff and are now embarking on a six-hour and four-orbit “fast rendezvous” to reach the International Space Station (ISS).

By a strange quirk of coincidence, today (3/14) happens to be “Pi Day”, and the mission of Ovchinin, Hague and Koch set off at 3:14 p.m. EDT Thursday (12:14 a.m. local time Friday). “Liftoff on #PiDay,” tweeted Hague in the hours before launch. “An engineer’s dream come true. Next stop, @Space_Station.” The trio are targeted to dock at the station’s Earth-facing (or “nadir”) Rassvet module at 9:07 p.m. EDT.

The Space Coast will be greeted by a rare spectacle on Friday evening (15 March), when United Launch Alliance (ULA) lofts the second-to-last member of its “single-stick” Delta IV fleet of boosters from Space Launch Complex (SLC)-37B at Cape Canaveral Air Force Station, Fla. The almost-six-decade-old pad—which last saw service to launch NASA’s Parker Solar Probe in August 2018—will reverberate to more than 1.8 million pounds (810,000 kg) of thrust from the Common Booster Core (CBC) and four strap-on solid-fueled rockets of the Delta IV Medium+ (5,4). Liftoff of ULA’s second mission of 2019 is scheduled for 6:56 p.m. EDT, at the opening of a 129-minute “window”, which closes at 9:05 p.m. Assuming a successful launch, the tenth Wideband Global Satcom (WGS-10) satellite will be released into supersynchronous orbit about 42 minutes into the flight, setting it up for a minimum 14 years supporting U.S. and allied warfighters.

In keeping with tradition, this particular Delta IV vehicle is dedicated to a late ULA employee; in this case, Kurt Huschle, who held critical roles during a 30-year aerospace career and was the electrical installations lead for the Delta IV.

Five months after an abortive attempt to reach the International Space Station (ISS), Russian cosmonaut Alexei Ovchinin and NASA’s Nick Hague will have a second chance to get to the sprawling orbital outpost on Thursday, 14 March, when they again launch from the Baikonur Cosmodrome in Kazakhstan. The pair originally flew aboard Soyuz MS-10 last October, but their mission was aborted during ascent and—thanks to the superb functionality of the launch escape system—the two men were plucked away from their failing Soyuz-FG booster and achieved a safe landing on the Kazakh steppe.

A quarter-century ago, this week, five astronauts aboard shuttle Columbia sailed through a mission which their launch announcer had earlier described as “the cutting edge of microgravity research”. STS-62 Commander John Casper, Pilot Andy Allen and Mission Specialists Pierre Thuot, Sam Gemar and Marsha Ivins spent 14 days in March 1994 overseeing a virtual miniature space station—with materials and space technology research, medical and biological experiments, solar physics instrumentation and robotics—in the shuttle’s cavernous payload bay and middeck. And for Ivins in particular, it would offer an early glimpse of the technology that she would one day use to install the U.S. Destiny lab onto the International Space Station (ISS).

In the coming weeks, NASA plans three periods of Extravehicular Activity (EVA) outside the International Space Station (ISS), involving four first-time spacewalkers from the United States and Canada. On the second of those three EVAs, on 29 March, U.S. astronauts Anne McClain and Christina Koch will make history by performing the first-ever all-female spacewalk. And according to NASA, Koch may remain aboard the station to achieve the second-longest single mission ever performed by a woman.

The first SpaceX Crew Dragon splashes down 200 miles off the coast of Florida at 8:45am EST March 8, 2019, closing out a successful uncrewed Demo-1 mission to the International Space Station for NASA.

This morning, SpaceX’s first Crew Dragon closed out an incredibly successful maiden voyage to and from the International Space Station (ISS), splashing down gently 230 miles off the coast of Cape Canaveral, Florida at 8:45am EST and wrapping up a week-long uncrewed flight test demonstration mission (Demo-1).

The Kuiper Belt is a vast region of rocky debris in the outer Solar System beyond Neptune, similar to the main asteroid belt between Mars and Jupiter. The objects in this belt – Kuiper Belt Objects (KBOs) – are ancient, left over from the formation of the Solar System billions of years ago, and range in size from a few hundred feet to a few thousand miles.

Pluto is the largest of these worlds, and while there is a great range in sizes of KBOs, a new study has shown that there is a surprising lack of the smallest objects less than a mile in size.
